By the way, for all those people who either worry about their high metabolic rate (or think they can always eat what they like and will never put on weight) your metabloic rate will most probably slow down as you get older. Very few people keep that very high rate through to adulthood. Until I was about 21 I was skinny as a rake and ate a ridiculous amount of food/beer. Now it has slowed down. I'm certainly not overweight because I work out a lot and eat healthily but I am sure if I didn't I would put weight on. Another thing to think about is that most teens do a lot of sport/exercise. When you get a job its gets harder to fit that in to your lifestyle which is why a lot of people start to pile on the pounds when they get older. I read the other day thet 1/3 of the population in the US will be obese by 2010. Something to worry about for you guys over the pond...
